Atenolol

I’m currently taking atenolol. I was given 25mg but I ended up cutting them and now I only take half each day. We are going to start ttc this month and I’ve seen that I shouldn’t take that if I get pregnant. I have a doctors apt on the 21st and I’m wondering if you ladies have any suggestions if there’s a certain one I should ask for or just tell him I need a pregnancy safe one
